If you have a look at the page you’ll see that it’s divided into two parts: on the left side you can control which kind of development opportunities are shown: you can limit the results to packages (or package sets) and to certain types of opportunities. The results will be shown on the right side.

I want to highlight two types of opportunities that might be interesting for you:

‘bitesize’ – bugs that are marked as ‘bitesize’ in Launchpad and deemed to be good targets for beginners

‘resolved-upstream‘ – bugs that have been fixed by the software authors but we don’t have the fix yet

lots and lots of others…

So once you picked an opportunity that looks interesting to you and made it work, you can propose the change for inclusion in Ubuntu. The great thing is that we have patch pilots working every day to get your changes reviewed and into Ubuntu. If you need help, just head to #ubuntu-devel (on irc.freenode.net) and check who’s piloting right now, the information is in the topic.
